Can the backlights for HVAC buttons be replaced?
 

Can the backlights for HVAC buttons on the Computer Climate Control be replaced? Not the dials but the four buttons along the bottom of the Computer Climate Control (Recirc Air, Fresh Air, A/C and Rear Def). I have a 2000 4X4 4dr Blazer LT and all but one is not lit when headlights are on.

Just wondered if it is possible to open up the Computer Climate Control module and change out the lights.

Thanks in advance.

You should be able to replace these. On my non-climate control Blazer, this pic shows a couple of the bulbs for the HVAC control panel (blue knob things). I would expect yours will have something similar.

I would guess that they are replaceable. What kind of bulbs they are, I'm not sure. Your best bet would be to pull the hvac controls off and look at the back. If you can find bulbs for them, take a pic and we should be able to help you find the correct replacements.
